3 Claims. (Cl. 188-406) This invention relates to operating means for the two left-hand brakes applied when the car brakes or the like, and is illustrated as emis left. parked. bodied in an automobile chassis having a set While one illustrative embodiment has been of four-wheel brakes. An object of the invendescribed in detail, it is not my intentionto 5 tion is to provide a simple and inexpensive syslimit the scope of the invention to that par- 50 tem of operatingconnections for the brakes, by ticular embodiment, or otherwise than by the a novel arrangement of cables which preferably terms of the appended claims. operate the brakes without equalization. I claim: 7 In the arrangement illustrated in the drawing, 1. A chassis having front brakes and rear 10 the right and left pairs of cables, passed over brakes, a pedal-operated lever having one. arm as suitable right and left direction-changing elewith a pair of cables connecting it to the -left ments if desired, are all brought together and front and left rear brakes and having another connected to asingle central lever operated by. arm with a pair of cables connecting it to the the driver, for example by being connected to right front and right rear brakes, an auxiliary 1 the usual service brake pedal. -I prefer to conlever, and a pair of auxiliary cables independent- 70 met at least two of the cables independently 1y connecting said auxiliary lever to two of said to an auxiliary operating device such as the first mentioned cables at points intermediate the usual emergency lever. pedal operated lever and the brakes.

The above and other objects and features of 2. A chassis having front brakes and rear sirable structural details, will be apparent from with a'pair ,of cables connecting it to the left the following description of the illustrative emfront and left rear brakes and having another bodiment shown in the accompanying drawing, arm with a pair of cables connecting it tothef in which: right front and right rear brakes, and an au"xil-' 35 The figure is a top plan view of the aboveiary lever independently connected to one of said 180;

The two left-hand cables are connected to one arm, and the two right-hand cables are connected to another arm, of a three-arm lever 36 pivotally fulcrumed ona cross member .of the chassis frame, and the third arm of which may be connected by means such as a rod or cable i 38 to the service pedal 40.

I prefer to connect cables 24 and 26, independently of lever 36, by means such as auxiliary o cables 42 secured thereto, to auxiliary operating means such as a bellcrank lever 44 pivoted on the frame cross member and connected by means such as a rod or cable 46 to the usual emergency lever 48.
